i got high rpm after i clean the throtle body LE5 with p0122 code anybody know why?

 

That's what happened to mine an I had to replace it

 

how do you fix it?

 

I have no idea. I was having problems with my throttle body. The car would drive by its self without me giving it it has. And wen it was in park the rpms would shoot up. So we took the tb off and cleaned it and when we put it back on it was even worse. So I just bought a lsj throttle body

Gas*

 

Sound to me like a faulty tb.

 

you need to re calibrate pcm ran into this issue with a buddies car brought it to my work re calibrated good to go
